Seattle Anal Cancer Prevention Program
Early Detection and Treatment of Anal Dysplasia
At Precision Proctology by Dr. Rodney Kratz, we offer a dedicated program focused on the early detection and treatment of anal dysplasia, the precancerous condition that can lead to anal cancer. Our program provides specialized screening using High-Resolution Anoscopy (HRA), the most advanced technique available to identify abnormal anal tissue caused by HPV. Through early detection and treatment, we aim to prevent anal cancer before it develops.
Why Anal Cancer Screening Matters
Anal cancer rates have increased in recent decades, particularly among patients with HPV infection or immune suppression. Many cases of anal cancer begin as anal intraepithelial neoplasia (AIN)—precancerous cellular changes that can be detected and treated early. Our program focuses on identifying and treating these lesions before cancer develops.
Evidence-Based Care
The ANCHOR Study The landmark ANCHOR Study demonstrated that treating high-grade anal dysplasia (HSIL) significantly reduces the risk of developing anal cancer. This study fundamentally changed the approach to anal cancer prevention by showing that screening and treatment of precancerous lesions saves lives. Our program follows these evidence-based screening and treatment strategies.
High-Resolution Anoscopy (HRA)
High-Resolution Anoscopy is a specialized procedure that uses magnification and enhanced visualization to evaluate the anal canal. This allows clinicians to: • Identify precancerous lesions • Perform targeted biopsies • Treat abnormal tissue early Most examinations take 20–30 minutes and are performed in the office.
Our Anal Dysplasia Team
Our program combines surgical expertise with dedicated HRA specialists. Rodney Kratz, MD, FASCRS Board-Certified Colon & Rectal Surgeon Dr. Kratz leads the program and provides advanced surgical care when needed. Teresa Vasicek, PA-C • ANCHOR study certified High-Resolution Anoscopy provider • Investigator in the ANCHOR study • Performs screening, biopsy, and dysplasia treatment
Who Should Be Screened?
Patients who may benefit from screening include: • HIV-positive individuals • Men who have sex with men • Patients with abnormal anal Pap tests • Individuals with HPV infection • Patients with cervical, vulvar, or vaginal dysplasia • Immunosuppressed individuals • Patients with persistent anal lesions Early screening allows abnormal cells to be treated before cancer develops.
Treatment of Anal Dysplasia
If abnormal tissue is detected, treatment may include: • Targeted biopsy • Ablation of precancerous lesions • Surveillance for recurrence Early treatment significantly reduces cancer risk.
